Q: I have had rectal problems for the past couple of years and I try to keep a slight gap at the back when I sit on the toilet. However, it felt like something fell on my back and I knew for sure it could not have been urine splashing on me. Later, I tried to check if urine splashes fell on me, but I couldn't tell. When I went the third time I saw one splash fall on the seat, so I was worried if this was happening all the time but I was unaware.

My questions are:

1. Do I have to have a shower and change anything that could have come in contact with me?

2. Are all of my prayers valid?

3. Have I made anything najis from touching that part of my body?

4. This is how most people use the toilet so should I tell my family members to be careful and sit all the way back.

Q: Is it permissible to have animal hide on the floor in one's house?
